Unrecognised joint penetration in treatment of femoral neck fractures.
Noordeen MH., Lavy CB., Briggs TW., Roos MF.
Screw devices used to treat fractures of the femoral neck are usually positioned under image-intensifier control, using anteroposterior and lateral views. The volume projected by these views is over 27% larger than the femoral head; the tips of screws so placed may be outside the femoral head. This can be avoided by placement within the central two-thirds of the head: we have designed a template which can confirm safe placement.
